<P>PROBLEM TO BE SOLVED: To provide a lubricating device for reducing agitation loss of a gear and efficiently improving a lubrication property and coolability according to the rotation state of the gear. <P>SOLUTION: In the lubricating device 1, a storage part 4 for storing refrigerant mixture oil 6 comprising lubricating oil 6b and a refrigerant 6a, a gear housing part 3 for housing a gear 2, and a partitioning part 5 for sectioning the storage part 4 and the gear housing part 3 are formed in a case 8 of a power transmission device. The partitioning part 5 includes a first communication hole 7a through which the refrigerant 6a in the refrigerant mixture oil 6 passes, and a second communication hole 7b through which the lubricating oil 6b in the refrigerant mixture oil 6 passes during high rotations of the gear 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
